FARKAS 8 v POWER TACKING DEVICE FOR UMBRELLAS Fi 1ed June 15, 1956 INVENTOR 11 17/16: Err/ids ATTORNEY Patented July 20, 1937 UNITED STATES POWER TACKING DEVICE FOR UMBRELLAS William Farkas, Brooklyn, N. Y., assignor of one-third to Benjamin Nemeth and one-third to Morris Nemeth, Brooklyn, N. Y.

Application June 15,

7 Claims.

This invention relates to new and useful improvements in a power tacking device for umbrellas, parasols, and the like.

The invention proposes the combination of an umbrella cover of cloth or similar material to which a plurality of clips have been secured with a sewing machine and which clips are adapted to be removably engaged on the rib frame of an umbrella or parasol. With this arrangement the umbrella cover may readily be removed from the frame when desired, or replaced or exchanged.

A further object of the invention resides in the specific construction of the clips so that they are adapted to be attached upon the umbrella cover with a conventional button sewing machine.

Still further the invention contemplates a particular coaction between the clips and the ribs by which the clips are prevented from moving longitudinally on the ribs.

Still further the invention proposes a construction of clips which may be slidable on the ribs and which, when desired, may be moved to a second position in which it is fixed against motion.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a bottom view of an umbrella with clips mounted thereon according to this invention.

Fig. 2 is a fragmentary vertical sectional view of the umbrella shown in Fig. 1.

Fig. 3 is a fragmentary enlarged sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a perspective view of one of the clips.

Fig. 5 is afragmentary perspective view of a portion of the rib frame of the umbrella.

Fig. 6 is a perspective view of a modified clip. Fig. 7 is another perspective view disclosing a still further modified clip.

Fig. 8 is another perspective view showing a still further modified clip applied to a portion of one of the ribs of the umbrella.

Fig. 9 is a transverse sectional view of the device shown in Fig. 8 but with the clip in a second position.

Fig. 10 is a plan view of one of the clips disclosing another modified form of the invention.

The power tacking device for umbrellas, according to this invention, comprises clips formed with openings simulating the openings of a but- 1936, Serial No. 85,225

ton so that a power machine may secure each clip in position in the same manner in which a button is secured.

In Figs. 1 and 2 an umbrella is shown which comprises covering material III to which clips H have been attached. 'I'hese clips are adapted to be engaged upon and removed from the ribs l2 of the frame of the umbrella. Each of the ribs I2 is of conventional U-shaped construction, as clearly shown in Figs. 3 and 5, except that portions l2 of the ribs to which the clips are engaged are formed with depressed areas. These depressed areas form shoulders I2 at the ends thereof. Thus, when the clips H are forced into position the edges of the clips engage these shoulders and so the clips are prevented from sliding.

The clip II is formed with apertures l3 upon the central portion thereof through which the needle of the sewing machine may pass during the stitching operation. In Fig. 3 stitches 14 are shown securing the clip I l to the umbrella covering material I 0. In Fig. 1 it should be noted that there are several clips on each of the ribs I! of the umbrella so that the covering material is properly held. For example, on each rib there may be a clip at the extremity thereof and other 'clips intermediate of the ends.

umbrella the covering material should preferably be held in position by a removable cap it which is threadedly engaged upon the central rod ll of At the top of the the umbrella. The conventional tubular slide I8 is mounted on the central rod to which the reinforcing ribs I9 are pivotally connected at one of their ends and atthe'other of their ends they are connected with the ribs in the regular way. The details of the umbrella will not be given in this. specification as such details are commonly known. The details of the sewing machine are also not given as button sewing machines are well known at the present time, and they are adapted to handle the clips identically in. the

same manner as buttons without any changes whatsoever.

Each of the clips II has a central portion II 4 which is provided with the apertures l3. This central portion connects with side arms li which are adapted to extend along the sides of.

bulged portions ll engaging the sides of the umbrella rib.

In Fig. 6 a-modified form of clip is shown, indicated by the reference numeral 2|, which distinguishes from the prior clip merely in the arrangement of the apertures 13' upon the central portion ll thereof. The edge portion I l is shown to be formed of two separate fingers. In other'respects this clip is identical to the one previously described and similar parts may be recognized by the identical reference numerals.

In Fig. 7 another form of clip is shown which comprises a very narrow central or top portion 3H connected with side arms 3| The lower portions of these side arms are formed with a plurality of bulged in portions 3 I The top portion 3| is of a width corresponding with the distance between the conventional button holes so that the sewing machine may secure-the clip I position by lines of stitches extending across the edges of the portion 3| These stitches are indicated by the dot and dash lines 32.

In Figs. 8 and.9 a modified form of the invention has been disclosed in which there is a clip consisting of a central portion di -connecting with side arm portions 4l These side arm portions are formed with an intermediate bowedin area and with bottom bowed-in edge portions 43. The compass between the central bowed-in areas 42 and .the edge bowed-in areas 43 is exactly sufiicient to accommodate and receive the rib ll of anaumbrella. When the clip is engaged in this position on the rib it may be shifted longitudinally along the rib.

The rib II is formed with caved-in portions 44 which communicate with the top edge thereof and .which connect with openings 45 in the side arms of the rib. The compass of the clip between the central portion and the bowedin side portions 42 is also sufiicient to just receive the rib H, as indicated in Fig. 9. The side walls of the clip .are formed with stamped out prongs 45 which are directed inwards and which are adapted to engage the openings'45 in the rib. Thus, the clip may be forced downwards so that the prongs 46 first ride through the recessed portions .44 and then engage into the openings 45. Thus, the clip is held in a fixed position upon the rib andcannot slide. It

'is possible to removeandshift theclip to other slide the clip along the rib until it hasreached its adjusted position after which it is forced down to the position shown in Fig. 9 in which the prongs 46 engage the openings 45 to hold the clip in fixed position. a

In Fig. 10 the central portion i I of the clip,

is shown with 3 apertures I3". I

While I have illustrated and described the'preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the umbrella ribs having depressions on opposite sides upon which said clips maybe releasably engaged.
